5.6. DATA TRANSMISSIONS DIAGNOSTIC
To readout diagnostics should be set SW1 microswitch to the configuration mode (see pt. OPERATION MODE).
Correctness of transmission proceed on RS232 interface and RS485/422 interface can be checked by readout the errors list by
ADAConfig Software from the converter memory. Frames error counter will be increased, in case of: improper speed set compared to
real speed of data transmission. Parity error counter will be count the errors which can arise in case of misrepresent bytes in
transmitted sign. This counter will not work in case of disable control parity. To check those counters press the button [Read
transmission errors], and to delete (zeroing of counters in the memory of the converter) press [Delete transmission errors].
In case of parity errors or frame errors, should be checked the ADA-4010A converter's configuration and correctness connection of
RS485 bus to RS485/422 port and RS232 device connected to the converter RS232 ports.
After finishing the diagnostics, the SW1 micro-switch should be set to run mode (see pt. OPERATION MODE).
6. OPERATION
ADA-4010A converter can operate in addressable mode and not addressable mode.
6.1. OPERATING IN NOT ADDRESSABLE MODE
ADA-4010A operates as baud rate and data format converters in not addressable mode and lets to set different baud rates and data
formats on RS232 and RS485/422 interfaces.
This allows connecting old devices operates with not configure baud rate and data format on RS485 bus, where operate devices with
different baud rate or different data format.
6.2. OPERATING IN ADDRESSABLE MODE
In this mode ADA-4010A operates as baud rate and data format converters and lets to connect not addressable RS322 interface
devices transmitting data with different baud rates and data frames format to RS485 bus, and thus lets to cooperate with not
addressable devices.
Example connection is shown on figures below.
Frame of protocol for not addressable devices connected to RS232 port of ADA-4010A on RS485 bus should be created in the
following way:
ADDRESS ADA-4010A FRAME OF PROTOCOL FOR NOT ADDRESSABLE DEVICES
Where:
ADDRESS ADA-4010A - one byte of address from 1-255 scope - set in the memory of ADA-4010A
during configuration in use of ADAConfig,
FRAME OF NOT ADDRESSABLE DEVICES - free sequence of bytes containing the appropriate frame of connected device
of the RS232 port. Not longer than 950 bytes.
11
ADA-4010A
ADA-4010A converter with set up addressing is listening constantly to frame on RS485 bus via RS485/22 port. If received frame
contains byte of address equal to converter address then another bytes of frame are received right up to silence on RS-485 bus equal
to 'space between frames in signs'. If the frame is received correctly, the address byte is deleted and transmitted over as typical to the
RS232 port.
In case of errors in received frame, it isn't transmitted to RS232 port. In this case should be send the previous frame. The frame
received from device connected to RS232 port is being tested of transmission errors and in case of their missing converter adds
address to beginning of frame and send it to RS-485 bus via RS485/RS422 port. Frame containing errors isn't being transmitted to
RS232 port. In case of transmitting of frames containing more than 950 bytes converter receive only 950 bytes and next are ignored.
ADA-4010A was equipped with separate buffers for RS232 and RS485/422 ports, therefore converter can operate at full duplex mode
on RS-422 and RS-485 (RS2) 4-wire bus.
Additionally, can be set data flow control for RS485/RS422 and RS232 interfaces according to pt. CONFIGURATION BY THE USE OF
ADACONFIG.
On a picture below are shown the possibilities of using the addressable ADA-4010A baud rate converter.

7. CHANGES IN THE SOFTWARE
From CPU 2.0 and software 000.007 versions, was added:
- flow data control by the use of DE signal for RS485/RS422 interfaces and flow data control of RS232 signal for RS232 interface.
Description of using new option is in pt. CONFIGURATION BY THE USE OF ADACONFIG,
- converter operating mode factory default is set by the use of SW1 micro-switch, see pt. OPERATING MODE
ATTENTION!!!
THE SOFTWARE IN 0.007 VERSION AND UPPER WILL NOT OPERATE WITH THE CONVERTERS WITH CPU 1.0. VERSION.
IN CASE OF UPDATE THE SOFTWARE TO 0.007 VERSION AND UPPER IN THE CONVERTERS WITH CPU 1.0. VERSION
PLEASE CONTACT TO SERVICE.
